The ring opening reactions of six known or new 2,2-dichlorocyclopropyl phenyl sulfides have been carried out with potassium t-butoxide in t butylalcohol and with pyridine. The products were enynes, butadienes, allenes and, as minor products, α,β-unsaturated aldehydes containing the phenylmercapto group. Reaction of a mixture of cis- and trans-1,1-dichloro-2-methyl-3-phenylmercaptocyclopropane (2)

water, furnished exclusively the (Z)- and ( E )-vinyl sulfides, respectively. The regio- and stereochemistry of the intermediates generated, (Z)- and ( E )-phenylthio vinyl alanates, were determined by capture with iodine, which afforded the corresponding ( E )- and (Z)-1-iodo-1-phenylthio-2-organoyl ethenes. Reactions of the ( E )-iodo(thio)ketene acetals with n-BuLi followed by addition of hexanal
